* move the font related classes to a fonts/ directory
* break out fontchooser into it's own header
* make things use properly
* make some things private; merge in pino's additional private changes as well so that nothing got lost in this move despite us working at the same time =)

will mv the kfontchooser file in a moment; svn doesn't like add's and mv's combined though.. so .. two phase commit ;P
